DGS-1250 Series Gigabit Ethernet Smart Managed Switch CLI Reference Guide Usage Guideline A full-duplex port is considered to have a point-to-point connection; on the opposite, a half-duplex port is considered to have a shared connection .The port can't transit into forwarding state rapidly by setting link type to shared-media. Hence, auto-determined of link-type by the STP module is recommended. This configuration will take effect for all the spanning-tree modes. Example This example shows how to configure the link type to point-to-point on port 7. Switch# configure terminal Switch(config)# interface eth1/0/7 Switch(config-if)# spanning-tree link-type point-to-point Switch(config-if)# 58-11 spanning-tree mode This command is used to configure the STP mode. Use the no form of this command to revert to the default setting. spanning-tree mode {mstp | rstp |stp} no spanning-tree mode Parameters mstp rstp stp Specifies the Multiple Spanning Tree Protocol (MSTP). Specifies the Rapid Spanning Tree Protocol (RSTP). Specifies the Spanning Tree Protocol (IEEE 802.1D Compatible) Default By default, this mode is rstp. Command Mode Global Configuration Mode. Usage Guideline If the mode is configured as STP or RSTP, all currently running MSTP instances will be cancelled automatically. If the newly configured mode is changed from the previous one, the spanning-tree state machine will restart again, therefore all of the stable spanning-tree port states will transit into discarding states. Example This example shows how to configure the running version of the STP module to RSTP.. Switch# configure terminal Switch(config)# spanning-tree mode rstp Switch(config)# 458
